I'm new here and am familiar with the flapper system as fitted to the Rover SD1 Efi cars. If your system is similar, then from your description including wet spark plugs and refusing to fire, it sounds like gross overfuelling.
Two main causes can be:
* Cold start system remains on after cranking flooding the intake with fuel..
* ECU faulty, Ditto.
You can read about the CS system on my website along with descriptions of all the other key Efi components from this index:
Rover SD1 Efi System Components
Other things such as blocked fuel return line from fuel pressure regulator, blocked air filter, malajusted AFM (flapper), throttle pot eletrically noisy, etc, could be considered.
You will also find a basic Efi test program on my website aimed mainly at air leaks, but it touches other issues as well.
Most of the main articles you'll see are in PDF format so feel free to browse and download anything you find useful.
